ELECTRIC STRlKlNG AND REPEATING CLOCK.

SPECIFICATION forming part of Letters Patent No. 402,329, dated April 30, 1889.

Application filed October 9,1888. Serial No, 287,661 (No model) To all whom it may concern.-

Be it known that we, ALPHONSE M. J. JAN- SEN and VINCENT J'. A. M. JANsEN, of San \Villibrordo, Ouracoa, have invented a new and Improved Electrical Clock, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of our improved electrical clock, and Fig. 2 is a vertical transverse section with the repeating mechanism omitted.

The object of the invention is to construct a clock in which the time-movement as well as the striking mechanism will be operated by electricity.

Our invention consists, in the combination, with an impulse-wheel and pallets, of a lever operated by an electro-magnet and adapted to propel the impulse-wheel; also, in the combination with the time-movement of a strike wheel connected with the said tin1e1novement so as to be moved intermittently, the wheel being provided with electrical contacts for completing the bell-circuit.

It also further consists in the combination, with. the strike-wheel and its actuating mechanism, of a wheel carrying a series of repeat ing-wheels, one for each hour, the repeatingwheels being constructed to make as many electrical contacts during every revolution as are necessary to make the stroke for the hour.

In the frame A is journaled an arbor, 13, upon which is secured an impulse-wheel, 0. Above the said wheel and in the said frame A is journaled an arbor, a, carrying the pallets l) b, which engage the impulse-wheel C. To the arbor a is secured a lever, D, one end of which carries the usual fork, c, for engaging the roller (Z of the balance The opposite end of the lever D is bent downward in the plane of the lever at an angle of about sixty degrees, and is provided with an electrical contactpoint, c, and with insulation f upon opposite sides of the contact-point. The arbor 5/ of the balance E is journalcd in the frame A, and said balance is provided with the usual hainspring, 71.

To an L-shapcd frame, F, held by a fixed support near the frame A, is attached an electro-magnet, G, and to the upright arm 2- of the said frame F is pivoted an armature-lever,j, the free end of which is provided with a contact-point, 7t, capable of touching the contactpoint e of the lever D. To the upright i is secured a flat spring, I, which tends to lift the armature-lever. The armaturelever holds the armature on within the influence of the magnet G, and the said magnet G is connected up in-the circuit of the battery H, so that the current passes from the battery to the magnet, thcnce to the armature-lever j, thence to the lever D, and through the arbor a to the battery.

The balance E being set in vibration, the lever D is oscillated in the usual way, and as the contactpoint c is carried upward it strikes the contact-point 7;, carried by the lever j, completing the electric circuit of the battery II and causing the armature m to drop upon the magnet G, thereby giving the lever D an impulse which carries forward the leverD after the ari'naturc-lever j has completed its stroke, thereby interrupting the electric circuit and causing the armatur -lever to be released, when the spring Z carries it back to the point of starting. W'hen the return movement of the balance E carries the lever D in the opposite direction, the contact-point e is again brought into" contact with the point 7c on the armaturedeverj, and the operation just described. is repeated.

In the frame A is journaled a spur-wheel, I, which receives motion from a spur-wheel, J, on the arbor B through the intermediate wheel, 71., also journaled in the frame A. The size of the wheel I relative to the wheel 3' is such as to cause the said wheel I to revolve once in a minute. From the boss of the wheel I projects a stud, c, which engages a tooth of the wheel K once during each revolution of the 9 wheel I, and the wheel K is provided with sixty teeth, so that it makes one revolution in one hour.

Upon the arbor p, journaled in the frame A, is secured. a wheel, 11.,carrying an insulating-- rim, q, provided with contact-bars r, which are in electrical connection with the wheel L. The periphery of the wheel L is divided into twelve divisions, representing the twelve hon rs, and the said divisions are provided with from one to twelve contact-bars 1', respectively, according to their location. Between each set of contact-bars a ratchet-tooth, 3, projects from the periphery of the said wheel. A spring-pawl, t, is attached to the side of the frame A and adapted to engage the ratchet s. The pawl is provided with a side spring, a, arranged to contact with the bars 4" as they are carried pastthe said spring a.

To the arbor p is secured a ratchet-wheel, 1), having twelve teeth corresponding with the twelve divisions in the periphery of the wheel L, and to the side of the wheel K is secured an arm, w, of insulating material, which engages the ratchet-wheel v and is capable of moving saidratchet-Wheel one notch at a time. The arbor p is provided with a knob on the end thereof for convenience in setting the clockwork.

To an angle-arm, a, projecting from the frame A is secured an electrical contactspring, c which is electrically insulated from the said arm. The battery II is connected by one of itspoles with the spring 0, and by the other pole with one terminal of the mechanism of'a single-stroke electric bell, M, of ordinary construction, the other terminal'of the said bell being connected electrically with the spring 15. r

As the Wheel K is engaged by thepin 0, carried by the wheel I, While the arm 20 is in engagement with the ratchet-wheel t, the wheel L is moved forward one-twelfth of a revolution, thereby carrying one of the twelve spaces of its periphery under the pawltand past the spring a. In the passage of a section of the periphery of the wheel L under the spring a the contact-bars r touch the said spring and complete as many electrical contacts as are necessary to secure the required number of strokes of the bell for the hour represented by that particular section of the wheel L. The wheel L, by virtue of its connection with the time-movement, is carried forward with a speed controlled entirely by the movement of the wheel K.

In the complete clock shown in Fig. 1 arepeating-wheel, L, is secured tothe arbor 10 outside of thewheel L, and upon the face of the said repeating-wheel L, opposite each hour-space of rim q of the wheel L, is'pivoted a circuit-controlling wheel, d, on a screw, 6, and to the-side of the said wheel is attached a ratchet-wheehf, having twelve ratchet teeth. In the periphery of the wheel are arranged contact-points g, which are in electrical communication with the wheel, but insulated from each other by an insulating band, it. Each wheel pl carries as many contact-points g as are necessary for producing the number of strokes of the bell required for the hour represented by the wheel. For eX- ample, the wheel d representing one'oclock, has one contact-point g, the wheel representing two oclock has two contact-points g, &c. Each wheel d is provided withalug, d which is engaged by the spring m once during each revolution of the wheel cl, thus preventing the Wheel from turning beyond the prescribed limit.

Upon a fixed support near the frame A is secured a right-angled frame, N, which sup- .ports the electro-magnet O, and also the vibratory armature c", and the insulating-piece j, which supports the contactspring It. To the free end of the vibratory armature t" is pivoted a hooked pawl, Z, which engages the ratchet-wheel f An arm, P, attached to the frame N, extends toward the center of the wheel L and carries a contact spring, m which touches the periphery of the wheel d.

When the repeating-wheel L is'turned, it brings one of wheels d into engagement with the contact-spring m, which also brings the ratchet-wheel f belonging to that wheel into engagement with the pawl Z.

One pole of the battery H is connectedwith a push-button, n, which in turn is connected with a'binding-post, 0, on the frame N. The binding-post 0 is connected through the upright of the saidframe with the vibratory armature c". From the said armature the circuit is through the contact-spring k, the mag net 0, back to the opposite pole of the bat tery. Upon pressing the push-button n the circuit of the magnet O is closed andthe armature i set in vibration, causing the pawl Z to engage the teeth of the ratchet-wheel f in succession, thus rotating the wheel d.

The contact-spring'm, which touches the periphery of the wheel (1, is connectedelec trically with one pole of the battery H the other pole of the battery being connected electrically with the electric bell M, which, in turn, is'connected with the frame of the clock. As the contact-pieces g" pass the end of the contact-spring m, the circuit 'of the bell M is closed,"caus'ing the bell-hammer to strike the bell, the number of strokes corresponding with the number of contact-points g carried by the wheel. It will thus be seen that at any time when it is desired to cause the clock to strike the hour it is only necessary to press the button n.

One or more bells, M, may be connected with the repeating part of the clock, and one or more push-buttons with suitable circuit may be' provided, so that the clock may be made to repeat at distant points.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent-e 1. In an electric clock, the combination of the impulse-wheel O, pallets b b, the arbor a, carrying the said pallets, the lever D, provided with a contact-point, c, the balance-wheel and roller E d, for engaging said lever, the electro-magnet G, and the armature-leverj,
